Is there a Matlab function to convert a plot into a matrix or image?

10 views (last 30 days)
If I write something like this
x=1:128;
y=exp(-x.^2/128)
p=plot(x,y); % I want to convert the plot on the screen to a matrix or image under program control.
can I write Matlab code to convert the plot I see on the screen to a matrix or image? I don't want to do this manually with "Save As", that is, I want to be able to automatically convert a series of plots into matrices or images.

I assume you mean that you want to do it programatically, as opposed to interactively.
I'm a creature of habit, and I generally use the print function to save a figure to an image file. There are other options, such as exportgraphics and saveas.
